3 Claims.. (cram-97 1 Ihis invention relates to holders forsacks, bags and the like; the primary object being to provide a relatively inexpensive, light weight,

, easily operated device having ar'cuate arms swingably mounted for movement toward-and away from each other and adapted to receive the bag to be held and to hold the mouth there of in an open condition while the sack is being filled.

, It is the most important object of the present invention to provide a sack holder that includes an upright standard having the aforesaid arms swingably secured thereto, and a base at the lower end'thereof for supporting the standard and for mounting a swingable foot pedal thatis operably joined with the arms to impart swinging movement thereto as the pedal is actuated.

Another important object ofthe present invention is the provision of a sackholder having means on the standard and connected-with the structure interconnecting the swingable arms and the swingable foot pedal foryielda-bly holding the arms biased apart whereby to hold the open mouth of the sack in astretched condition while the sack is being filled.

Other objects include the way in which a crank is pivotally secured to the standard and to the arms as well as the foot pedal by linkage so as to provide the proper leverage, and the way in which the arms are mounted on a platelike head on theupper end of the-standard for swinging movement thereon in a'common horizontal plane.

Many more minor objects will be made clear or 'become apparent as the following specification progresses, reference being-had to the accompanying drawing, wherein:

Figure 1 is a front perspective View of a sack holder made pursuant to my present invention.

Fig. 2 is a top plan view thereof showing the path of movement of the swingable sackholding arms; and

Fig. 3 is a fragmentary, cross-sectional view taken on irregular line III-III of Fig. 2.

The sack holder of this invention is well illustrated in the drawing and includes an elongated, preferably tubular, upright standard l9, mounted at the lowermost end thereof upon a U-shaped base broadly designated by the numeral I2.

Base I2 is provided with a pair. of substantially parallel, elongated legs l4 and I6 and an elongated bight 18, all three parts of which are preferably L-shaped in cross-section as shown in Fig. 1 for strength and rigidity. The lowermost endofthe standard It is secured directly to-the big-ht I8 intermediate the ends of the latter. Additional strength and sturdi-ness is attained through the medium of a pair oi -elongated braces Zllthat are joined at the uppermost end thereof directly tostandard lflwell above bight l8 ofbase I2 and at the lowermost ends of bracesZB to legs I l-and Ifiintermediatethe ends of the latter. Accordingly, the braces 20 converge as the standard I0 is-approached and the'lowermost ends of the braces 20: are spaced outwardly away from the lowermost end of 'the standard I ll.

A head, broadly designated by the numeral 22, including a fiat, horizontalpl'ate 22-; and a depending web 26 issecured directly to the standard lo -at the uppermost end thereof. Head 22 carries a pairofpreferably identical arcuate arms 28 that are substantially semi-circular through the mediumof a-link3fl: for each arm 28: respectively: The links-3D- overlie the-plate 2 1 and are pivotally secured thereto through the medium of spaced-apart, vertical bolts. or the like 32.

One end of each arm 28 is secured 'directlyto its corresponding link 30.'on one side of the piv otal bolt 32thereof. Each of .the arms'ZB. is provided with a plurality of upwardly. extending sharpened pins 3t spaced along the. length there-. of and-onthe outermost edgesof. arms 28;

The. standard. I!) is. provided-withapair of spacedeapart, substantially parallel, laterally extending brackets 36 and 38' and. leg id of base I2 is. likewise provided with an elongated. bracket 40, extending laterally beyond bight. [8 in thesame directionas brackets 36 and..38 The brackets 33 andAil: pivotally carry an. elongated, hOIiZOIIt&1.Shafi)E4Z- having an elongated. bar" 44 rigidly'secured to one. end thereof; and: in turn provided with a foot: pedal 46 at the: outermost free end. of bar M It. is noted thatthe bar A l extends from the shaft 42. in.- the same direction as .the leg Mof base [2. That end of the shaft 42. oppositeto; the bar A l has a. short, linkv lilv rigidly secured thereto.

The bracket. 36- on standard It has a substantially T'-shaped: crank 50 pivotally secured theretoas'at 52. Anelongated reciprocable rod 54 has both ends; thereof. bifurcated, the: uppermost .end pivotally receiving one leg of the crank 50 as at 56 and the lowermost end of the rod 54 pivotally receiving the short link 48 as at 58. Another leg I of the crank 50 pivotally receives a pair of identical links 6|] as at 62 for each link 30 respectively. Each link 60 is pivotally secured to 2. correspond- 3 ing link 30 through the medium of a vertical bolt or the like 64 on that side of the pivotal bolt 32 opposite to the corresponding arm 28.

A vertical tube 66 is carried by the standard In adjacent the uppermost ends of the braces 20, which tube 66 loosely receives an elongated bolt 68 having a nut 10 threadably secured to the uppermost end thereof above tube 66. The lowermost end of the bolt 68 extending below tube 66 receives one end of a spring 12 that is in turn secured directly to the rod 54 adjacent the lowermost end of the latter.

When it is desired to place a sack or bag in a holding position with respect to the arms 28, the latter are caused to swing together against the bias of spring 12 as illustrated by dotted lines in Fig. 2 of the drawing. This springing movement of arms 28 toward each other is accomplished through the medium of downward movement on foot pedal 46 which swings bar 44 and the shaft 42 connected thereto as the latter rotates within the supporting brackets 38 and 48 therefor. Such rotative movement of the shaft 42 causes the short link 48 to swing toward the standard 10 and the rod 54 to reciprocate downwardly, all against the action of spring 12. As rod 54 so moves, crank 50 is caused to swing on the pivot 52 of bracket 36 which in turn retracts the links 60 in the manner illustrated by dotted lines in Fig. 2 and imparts swinging movement to the of the sack around the arms 28 in substantially circumscribing relationship thereto and at the same time secure the sack to the arms 28 by hooking the sack in sharpened pins 34 of arms 28. The operator thereupon releases the pressure upon foot pedal 46 and the spring 12 comes into operation to reverse the aforesaid movements and force the arms 28 outwardly toward the full line position illustrated in Figs. 1 and 2.

While the sack is being filled and as the same hangs below arms 28 resting upon any suitable supporting surface for base 12, the spring i2 will hold the arms 26 in a condition for maintaining the open end of the sack substantially circular. As soon as the sack is filled, the operator again presses downwardly upon the foot pedal 46 to move the arms 28 to a point where the sack may be released from the pins 34 and the sack may thereupon be tied and moved to a point of storage or loading from between the legs l4 and 16 of base l2.

It is seen that the standard l and all of its component parts are well supported by the base l2 against tipping movement in any direction and that neither the legs I4 and 46 nor the braces 26 will interfere with the sack being filled and depending from the arms 28. If desired, the base [2 may be rigidly secured to a supporting surface or to a mobile support of any suitable character. In any event, the entire sack holder is inexpensive to manufacture, easy to manipulate and capable of holding the sacks in a condition for filling without operator attention while the filling takes place. The sacks may be easily and quickly applied to the arms 28 and removed therefrom.

Many details of construction may be changed or varied within the spirit of this invention and therefore, it is desired to be limited only by the scope of the appended claims.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

A sack holder comprising an elongated, upright standard having a base at the lowermost end thereof; a horizontal shaft rotatably carried by said base and said standard; a foot pedal secured to one end of said shaft; a head on the uppermost end of the standard; a pair of arouate, sack-holding arms mounted at one end thereof on said head for swinging movement on spaced, vertical axes toward and away from each other; and structure operably interconnecting the shaft and said arms for swinging the latter on actuation of said foot pedal.
